c The present day construction ofpaving machines generally includescharglnganeans for the mixing drum in the form of a pivoted loading skipwhich is located endwise -wit'h 1;; respect'to the machine; This loadingskip is adapted to assume a position on theground wherein it receivesaggregates to-be charged into the mixer, and issusceptible to opera- 7tion so that it may be moved into a position in which the aggregates-aredischarged into the drum. In thenow known types of load ing skips, alarge amount of apparatus is necessarily included in the paving machinea with the peration of the skip as their only '5 function. a a I a Ipropose by the paving machine'that is directly associated with theskip'and its operation. In attaining this end, I: employ a skip ofparticnlarly novel construction which is characterized by the utmostsimplicity.

More particularly, I avail of rolling members in the form of lobes whichare rigidly aflixed to the skip itself and' which, upon movement oninclined trackwaysincorpo- 1 rated into the COIlStIllCt'lOIl of themixer, move theloading skip from a loadingto adiseharging position,'or'vice versa. f

A particularly noteworthy feature of'the invention is thearrangementof'skip hoist cable means employed in conjunction-with thelobes on the skip. This feature minimizes to the greatest possibleextent, the amount a) of force needed to elevatethe skip. lnf the oldconstruction very often 'a'la rge amount of energy was expended due tothe'pivoted arrangement of the skip wherein pull was exerted from thepoint below the radial l center of the skips arcuate travel. My novelconstruction completely obviates this condition. A more particularobject of the invention is the provision-of means for insuring thesmoothand even movement of the skip 1 during its operation. In achievingthis object stabilizing cables are employed which are properly arrangedwith respect to the track ways and lobes to govern movementof the I r nas applied'to a. pav ng machlne, parts or the latterbeing pmittedi:

latter with the former. Preferably two cables are employed inconjunction with each this inventionto eliminate to a certain degree theapparatus included in lobe andits' corresponding way. One cable has oneend fast to the upper end or" the way with its other end anchoredadjacent to the "extremity of the lobe resting on the track {when theskip is in loading position, while "theother cable-has one'end affixedto the lower "end of'tlie track and is passed over the lobewith'itsother end anchored to the skip adjacent the other extremity ofthecnrb working surface of the lobe member. 4

Another point'of novelty included in a skip made inaccordance with myinvention that is worthy oi stressing", is the particular constrnctionof the skip itself. 7 This member includes" awide'o'pen noutli which isadapted 'to"rece1ve'- theaggregates and has at its other end aconstricted throat or neck portion term nating in a d scharge opening.The embodiment of these last mentioned features in my novel skipenableit to assume a position in whichthejcomplete discharge of the aggrej'gatesinto thedru n is assured. For the purpose ofjinsnring theoperation of the lobes on a track during all stages of operation and topositively-inhibit their leaving said. -track 'ways,-their latter partsare provided with flanges which prevent any sidewise motion of the lobemembers. In preferred ,Fuither, more detailed objects andadvantages,jwill in part become apparent and in part behereinafterstated, as the "description 'of'th'e invention proceeds For a full andi'more complete understand ng thereof, referen'ce may be had to thefollowing description and accompanying drawings, in which;-
